A C4-2 cell line was treated with 20 nM NVP2 or 20 nM NVP2 + 20 µM OSMI-4 for four hours, fractions isolated and samples analyzed using western blot. B Inhibition of CDK9 using NVP2 induces DNA damage in prostate cancer cells as measured using phosphorylation of H2AX. C, D Cells were treated for 24 h and analyzed using western blotBack to article page
